Changes in the diameters of individual follicular structures on ovaries were measured by transrectal ultrasonography for 29 to 40 days and the plasma concentrations of luteinising hormone (LH) follicle-stimulating hormone (FSH), progesterone and oestradiol-17 beta were determined in four cows with ovarian cysts. When these structures decreased in size, new follicular structures appeared and developed into cysts. Progesterone concentrations in plasma were below 1.0 ng ml-1 during the experimental periods. Plasma concentrations of oestradiol-17 beta fluctuated. The mean concentration of oestradiol-17 beta in plasma differed (P < 0.01) depending on the stage of the cyst. No preovulatory surges of LH were detected during the developmental stage of the cysts.
通过经直肠超声检查对4头患有卵巢囊肿的奶牛的卵巢上单个卵泡结构的直径变化进行了29至40天的测量，并测定了血浆中促黄体生成素（LH）、促卵泡生成素（FSH）、孕酮和雌二醇-17β的浓度。当这些结构尺寸缩小时，新的卵泡结构出现并发展为囊肿。实验期间血浆中孕酮浓度低于1.0 ng/ml。血浆中雌二醇-17β的浓度波动。血浆中雌二醇-17β的平均浓度因囊肿阶段不同而有差异（P<0.01）。在囊肿发育阶段未检测到LH的排卵前高峰。
